These motors gradually slow up, and the slower speed causes motor to overheat.
Reset is supposed to detect high heat, but in any case, the motors go bad.
Used to be, there was a motor shop in town and they would rewind motors, but today we throw all the copper and metal into landfill unless old disposal is taken to recycle center and shipped to Bangladesh for dis-assembly and salvage.
Check that your wall switch has power, and that switch is good, and there is no loose wire.
Also check for loose wiring at disposal.
If reset is tripped out and won't reset, then disposal is bad.
Tips for installing new disposal:
Here are basic disposal parts:
1) Sink basket that connects to sink and is held with 3 screws from below.
2) Disposal body which connects to sink basket using metal ring.
3) Rubber washer between disposal and sink basket.
4) Dishwasher connects to upper part of disposal with a hose.
5) Electric wire coming from disposal switch connects to disposal near red reset button.
6) Tubular drain pipe connects to side of disposal
When I worked apartment maintenance, we replaced disposal with same size and brand disposal.
That way we didn't have to change out sink basket or move pipes around under the sink.
How to: Disconnect 2 nuts on p-trap and trap falls loose.
Using hammer and screwdriver, rotate steel connector disk that holds disposal to sink basket, and disposal comes off.
Before installing new disposal.
Attach electric wire to new disposal, black wire to black and white to white and ground to green screw or wrap around screw cover, and push in red reset button.
Attach dishwasher tube to new disposal. Knock out plug inside dishwasher opening.
Lift new disposal up into place, and attach to old sink basket.
There is a rubber washer between disposal and sink basket, Use new washer.
Connector ring catches at three points, all three have to connect.
You can use bottle jack to lift disposal if you have problem.
Re-assemble tubular pipe.
Image shows direction for connecting new disposal.
If this is your home, you want new sink basket that comes with new disposal because it looks shiny and new.
Buy a tub of plumbers putty also.
Remove 3 screws that hold sink basket, remove basket and clean sink opening.
Put finger-size roll of plumbers putty around sink opening, and then push new strainer basket into plumbers putty.
Tighten basket from below, wipe away excess putty around sink opening.
Install new disposal as described above.
Tips for tubular pipes:
When taking apart tubular pipes, start at p-trap and take apart as few pieces as needed to do job.
On image above, loosen both upper and lower nuts, trap falls loose, and then work on disposal.
Any tubular drain pipe that gets moved while working under sink needs to be disassembled, cleaned and re-assembled.
Metal pipes have rubber washer >> always use new rubber washers.
Plastic pipes have plastic washers > plastic washers can be cleaned and re-used.
Plastic washers have flat side that goes toward nut, tapered side away from nut.
When reassembling tubular pipe, we use rectorseal on washers and joints.
Slap a good amount on washer just before pushing washer in place and attaching nut.
Rectorseal will ensure tubular drain pipes won't leak.
